Highlighting its expertise in celestial complications, Jaeger-LeCoultre reinterprets the Calibre 945 which displays the constellations on the wrist that can be seen in real time in the sky. It unites to this unique display a minute repeater and is further elevated by a Cosmotourbillon. The shape of the filigree forming the outer section of the dome, echoes the lines that link the stars to form constellations.
